I’ve got four mother and babe style bobbins on my lace pillow at the moment. Christine and David Springett in their book ‘Success to the lace pillow’ define mother and babe bobbins as ‘miniature bobbin or bobbins enclosed in a pierced shank’. Three of the bobbins in the image would definitely fit that classification. They would probably describe the wooden bobbin as a lantern as it encloses small beads in a pierced shank. However it is also a whittled bobbin, which they describe separately, and the bobbin and beads were probably carved from a single piece of wood. T L Huetson in his book ‘Lace and bobbins’ describes all bobbins with pierced shanks as church window bobbins whether they contain a smaller baby bobbin, beads or nothing at all. The Springetts use the term church window only for bobbins with empty pierced shanks. I think the Springetts have done an enormous amount of research into bobbins and their makers and I find their use of the different terms helpful in describing bobbins more precisely so I think I’ll stick with their terminology.
